Curved Aluminium Windows

Arched Aluminium Windows

Duration Windows can produce curved aluminium windows using the latest computer controlled section bending machines. We can manufacture curved aluminium windows, top lites for doors, shaped and even circular windows.

We have invested in training, £50K bending machines in our factories and the vast collection of rollers and forms needed to bend all the different profiles in our extensive aluminium product range.
